Recently,
at the wind farm in Taian County, Anshan City, Liaoning Province, ZOOMLION's
self-developed world's largest tonnage all-terrain crane, ZAT40000H7, has
completed its first actual operation - successfully lifting the single-capacity
6.25MW turbine with a hub-centered height of 160m ( equivalent to the height of
a 50-story building) onshore wind turbine lifted into place. This feat not only
set a new record for the installation of ultra-high wind turbines in China, but
also marked the official entry of global onshore wind power construction into
the “4,000-ton all-ground lifting era”.
The
lifting project faces a double challenge: First, the operating space is
limited, mountain wind farm terrain is complex, the traditional crane transfer
needs to open up wide roads, construction costs and ecological damage risk
increases steeply; Second, the lifting efficiency and safety balance is
difficult, 160-meter high altitude operation needs to avoid wind load
fluctuations, jib deflection control and other more than 10 technical risks,
the traditional program relies on a number of auxiliary cranes to work
together, the cost of coordination is high.
ZAT40000H7
with three core advantages to break the situation:
First,
super lifting performance - as the world's first to meet the “190 meters height
7.0MW wind turbine lifting” 4000 tons of equipment, its main boom and the
enhanced boom combination jib length of 210 meters, can independently complete
the impeller. With a combined boom and jib length of 210 meters, it can
independently complete the integrated lifting of the impeller and nacelle,
reducing the need for overhead docking procedures.
Secondly,
all-terrain flexible transshipment - using a 10-axle compact chassis (width of
only 3 meters, length of 22.5 meters), together with the all-wheel steering
technology, the efficiency of transshipment has been increased by 60%, making
it easy to cope with the mountainous wind farms.
Thirdly,
smart and efficient construction --The first single-arm autonomous lifting technology,
through the AI dynamic balancing algorithm to achieve independent control of
the nacelle (150 tons) and impeller (nearly 130 tons) dual load, lifting
precision of ± 2 cm, shortening the construction cycle by 40%.
The
technological foresight of the equipment is reflected in the precise prediction
of the trend of wind power large-scale: the structural strength of its main arm
reserves space for lifting at a height of more than 190 meters, which can be
adapted to the future 8.0MW-class wind turbines; the modular counterweight
system realizes the coverage of the whole working conditions of “100-4000 tons
and 30-210 meters height”, which reduces the idle rate of equipment; the quick
disassembly mode makes the assembly and dismantling of the equipment easier and
faster, and the construction period is shortened by 40%. The modular
counterweight system realizes full working condition coverage of “100-4000
tons, 30-210 meters height”, reducing the idle rate of equipment; the quick
disassembling mode reduces the demand for assembling site by 40%, and a single
equipment can replace 3 traditional cranes, reducing carbon emission by 55%.
Niu
Xiaolu, chairman of Qingdao Tongli Crane & Hoisting Co., Ltd, who is
responsible for this hoisting, said directly: "Choosing ZAT40000H7 is a
key step in our layout of the northern wind power market. Its single-arm
autonomous lifting technology eliminates the scheduling costs of two auxiliary
cranes, and according to the project cycle, the comprehensive benefit is more
than 3 million yuan. More importantly, it allows us to realize ‘zero
outsourcing dependence’ for the first time in 160-meter-level aerial lifting,
and the construction discourse is completely reconstructed!"
As
a new member of ZOOMLION's “Super Crane” family, the birth of ZAT40000H7 is of
far-reaching significance: its rated lifting capacity of 4,000 tons, the
maximum lifting moment of 120,000 tons - meters, compared with the previous
generation of products to enhance the 67%; in the jib length, transfer speed,
intelligence level and other 12 core indicators to fully surpass the European
and American competitors. Competitors. More importantly, it promotes the
transformation of wind power construction from “multi-machine synergy” to
“single-machine omnipotence” mode, drives the cost of lifting services down by
25%, and injects new momentum for the global onshore wind power industry.
The
emergence of ZAT40000H7 not only fills the blank of 160-meter aerial lifting
equipment for global onshore wind power, but also establishes a
three-dimensional optimal solution of “safety-efficiency-cost” for the industry
with the cross-boundary fusion of “all-ground chassis+super lifting”. The
solution. In the future, ZOOMLION will continue to plough into the field of
wind power equipment intellectualization and greening, so that “China Hoisting”
will become the global benchmark of high-end equipment manufacturing.
